Force feedback system including multi-tasking graphical host environment
First Claim
1. A method of generating a haptic effect, the method comprising:
- executing at least two applications concurrently, wherein one of the applications is an active application;
receiving a user interaction with the active application, wherein the user interaction comprises a contact with a touch-sensitive panel;
in response to the contact, receiving a force effect command from the active application; and
in response to the received force effect command, generating the haptic effect on the touch-sensitive panel.

Abstract
A force feedback system provides components for use in a force feedback system including a host computer and a force feedback interface device. An architecture for a host computer allows multi-tasking application programs to interface with the force feedback device without conflicts. One embodiment of a force feedback device provides both relative position reporting and absolute position reporting to allow great flexibility. A different device embodiment provides relative position reporting device allowing maximum compatibility with existing software. Information such as ballistic parameters and screen size sent from the host to the force feedback device allow accurate mouse positions and graphical object positions to be determined in the force feedback environment. Force feedback effects and structures are further described, such as events and enclosures.
